摘要

目的：

观察脾虚高脂血症大鼠失功能高密度脂蛋白胆固醇(dyHDL)变化及香砂六君子汤的干预作用，从HDL“质”的变化，揭示香砂六君子汤对脾虚高脂血症大鼠dyHDL的影响及机制。

方法：

75只SPF级SD大鼠随机分为正常组，高脂组，脾虚高脂组，香砂六君子低、高剂量组(5.67，11.34 g·kg

－1

)，脾虚高脂组，香砂六君子低、高剂量组采用饮食不节加力竭游泳的复合方法造模15 d后，正常组喂饲基础饲料，高脂组，脾虚高脂组，香砂六君子、高剂量组喂饲高脂饲料。12周后，香砂六君子低、高剂量组给予相对剂量药物，正常组、高脂组、脾虚高脂组给予相应体积生理盐水。4周后，全自动生化分析仪检测血清总胆固醇(TC)，甘油三酯(TG)，低密度脂蛋白胆固醇(LDL-C)，高密度脂蛋白胆固醇(HDL-C)含量，间苯三酚法检测大鼠

-木糖排泄率，苏木素-伊红(HE)染色观察肝脏细胞形态变化，酶联免疫吸附测定(ELISA)检测血浆对氧磷酶1(PON1)，载脂蛋白A1(apoA1)，血清淀粉样蛋白A(SAA)含量，实时荧光定量PCR(Real-time PCR)检测大鼠肝脏PON1，apoA1，SAA mRNA表达水平。

结果：

与正常组比较，高脂组及脾虚高脂组大鼠血清TC

LDL-C水平明显升高(

0.05)，HDL-C水平明显降低(

0.05)，高脂组及脾虚高脂组大鼠血浆PON1，apoA1含量明显降低(

0.05)，SAA含量明显升高(

0.05)，肝脏组织SAA mRNA显著升高(

0.01)，PON1，apoA1 mRNA表达显著降低(

0.01)，高脂组及脾虚高脂组大鼠肝细胞肿大变圆、可见散在的脂肪空泡，且脾虚高脂组大鼠尿

-木糖排泄率明显降低(

0.05)。与高脂组及脾虚高脂组比较，香砂六君子汤低、高剂量组血清TC

LDL-C水平明显降低(

0.05)；HDL-C水平明显升高(

0.05)，血浆PON1，apoA1含量明显升高(

0.05)，SAA含量明显降低(

0.05)，肝脏组织SAA mRNA明显降低(

0.05)，apoA1 mRNA表达明显升高(

0.05)，肝脏细胞肿胀明显减轻、脂肪泡沫化减少。与高脂组相比，脾虚高脂组大鼠血浆中PON1，SAA含量明显降低(

0.05)，肝细胞肿胀明显、泡沫化加重。

结论：

脾虚状态下高脂血症大鼠脂质紊乱加重，香砂六君子汤干预后紊乱得以纠正，其作用机制可能与调控dyHDL相关mRNA及蛋白表达有关。

Abstract

Objective:

To observe the changes of dysfunctional high density lipoprotein cholesterol (dyHDL) and the intervention effect of Xiangsha Liu Junzitang in rats with spleen deficiency and hyperlipidemia

and reveal the effect and mechanism of Xiangsha Liu Junzitang on dyHDL in rats with spleen-deficiency hyperlipidemia.

Method:

Seventy-five SPF SD rats were randomly divided into normal group

high fat group

spleen deficiency and high fat group

Xiangsha Liu Junzitang low and high dose groups (5.67

11.34 g·kg

-1

). In the spleen deficiency and high fat group

as well as Xiangsha Liu Junzitang low and high dose groups

composite method of improper diet and exhaustive swimming was used for 15 days for modeling. After modeling for 15 days

normal group was fed with basic diet

while the high-fat group

spleen-deficiency and high-fat group

the Xiangsha Liu Junzitang low and high dose groups were fed with high-fat diet. After 12 weeks

the Xiangsha Liu Junzitang low dose and high dose groups received corresponding dosage of drugs

while normal group

high fat group and spleen deficiency high fat group received corresponding volume of normal saline. After 4 weeks

the contents of total cholesterol (TC)

triglyceride (TG)

low density lipoprotein cholesterol cholesterol (LDL-C)

and high density lipoprotein cholesterol(HDL-C)were detected by automatic biochemistry analyzer

while D-xylose excretion rate was measured by phloroglucinol method. The morphological changes of liver cells were observed by hematoxylin eosin (HE) staining. The level of PON1

apoA1 and SAA in plasma were detected by enzyme-linked immunosorbent assay (ELISA). Paraoxonase 1(PON1)

apolipoprotein A1 (apoA1) and serum amyloid protein A (SAA) gene expression in rats liver were detected by Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR).

Result:

As compared with normal group

the serum TC

and LDL-C levels were significantly increased in the high-fat group and spleen-deficiency high-fat group (

0.05)

and HDL-C levels were significantly lower (

0.05); the levels of PON1 and apoA1 in plasma were decreased (

0.05)

while the content of SAA was increased (

0.05); the expression of SAA gene in liver tissues was increased (

0.01)

and the expression levels of PON1 and apoA1 genes in liver tissues were significantly decreased (

0.01). In high-fat group and the spleen-deficiency and high-fat group

the hepatocytes were rounded and scattered

and scattered fat vacuoles were observed. In addition

the urinary

-xylose excretion rate was significantly decreased in the spleen-deficiency and high-fat group (

0.05). After the intervention with Xiangsha Liu Junzitang

the serum TC

LDL-C levels were significantly decreased (

0.05); HDL-C levels were significantly increased (

0.05); plasma PON1

apoA1 levels were increased (

0.05); the content of SAA was decreased (

0.05); the expression of SAA gene in liver tissues was decreased (

0.05); the expression of apoA1 gene was increased significantly (

0.05). Liver cells swelling was significantly alleviated and fat foaming was reduced. As compared with high-fat group

the plasma PON1 and SAA levels in the spleen-deficiency high-fat group were significantly lower (

0.05); hepatocyte swelling was obvious and foaming was aggravated.

Conclusion:

The lipid disorder in hyperlipidemia rats was aggravated by the spleen deficiency

but was corrected after intervention with Xiangsha Liu Junzitang. and its mechanism may be related to the regulation of the expression of dyHDL-related genes and protein.
